It takes 5 years for light to reach the earth from a star. Express the distance of star from the earth in (i) light year, (ii) km . Take speed of light `= 3xx10^8 m s^(-1)` and ` 1 year = 3.153 xx 10^7` s

Explanation

To solve the problem of finding the distance of a star from Earth in light years and kilometers, we can follow these steps:

### Step 1: Understand what a light year is
A light year is defined as the distance that light travels in one year.

### Step 2: Calculate the distance in light years
Since it takes 5 years for light to reach Earth from the star, the distance in light years is simply:
\[
